Steps to reproduce
1. Launch fullscreen landscape oriented app (for me, this is usually a game)
2. Exit app to return to homescreen (configured with screen orientation = 'default', but this also occurs with it set to 'force portrait')
3. Interact with a widget (in my case, I clicked the configure button on pure messenger widget, but this also occurs when clicking other widgets)
4. Screen temporarily switches to landscape mode
5. Folder preview icons get distorted

Screenshots and logcat attached

FYI, I'm using custom folder backgrounds here, but this happens with the stock background images as well (not sure that it makes a difference, but just saying)
